I would expect having red button "delete" which will delete all selected items. Instead, there is unexpected combobox with "delete selected" action.
There is already button "Add", so it sounds reasonable to have button "remove" next to it
this removes the drop down selection widget!
NOTE: we could add a button in template's `object-tools` block
but that will not be able to handle multiple selection. Also the
checkboxes for multiple selection are not rendered when
delete_selected is disabled. For reference see:
If the user wants to delete an object they will have to open each
object in a separate page and delete it from there!
